RV speed reducer performance testing device based on multi-sensor fusion

Abstract

The invention discloses an RV speed reducer performance testing device based on multi-sensor fusion. The device comprises a T-shaped groove bottom plate; an RV speed reducer is fixed to the T-shaped groove bottom plate through a speed reducer support; the RV speed reducer is connected with a servo motor through a motor flange; an output shaft of the servo motor is coaxially connected with an inputshaft of the RV speed reducer; an output shaft of the RV speed reducer is connected with the bottom end of a swing arm; a plurality of round holes are formed in the swing arm; the upper end of the swing arm is connected with a mass block; a communicated cavity is formed among the motor flange, the RV speed reducer and the swing arm, and the cavity is filled with a lubricating medium; an oil inlethole is formed in the motor flange; an oil outlet hole is formed in the swing arm; the oil inlet hole and the oil outlet hole are connected with the abrasive particle analyzer through oil pipes; an acoustic emission sensor is arranged beside the RV speed reducer; and a three-dimensional acceleration sensor and a patch type temperature sensor are mounted on the RV speed reducer. Omnibearing tracking detection can be performed on the state of the RV speed reducer in the whole life cycle, the abrasion state of the RV speed reducer is quantitatively evaluated in real time, and the performance ofthe RV speed reducer is comprehensively reflected.

Description

technical field [0001] The invention relates to the technical field of RV reducer performance testing, in particular to a RV reducer performance testing device based on multi-sensor fusion. Background technique [0002] RV reducer is a new type of reducer structure developed on the basis of traditional pendulum planetary transmission, which overcomes the shortcomings of general pendulum planetary transmission. Due to its small size, light weight, large transmission ratio range, A series of advantages such as long life, stable precision, high efficiency, and smooth transmission have attracted increasing attention at home and abroad, and are widely used in industrial robot joints. The quality of its transmission performance directly affects the overall performance of industrial robots. [0003] With the continuous improvement of industrial production automation and precision, the demand for industrial robots is also increasing rapidly. The running accuracy and reliability of ...

AI Technical Summary

Problems solved by technology

At present, most RV reducer performance test devices collect single information, can only detect the life of the RV reducer, cannot quantitatively evaluate the wear status of the reducer, and need to dismantle the machine to check the status of the reducer, and cannot monitor the RV reducer in real time and comprehensively. It is difficult to meet the requirements of RV reducer performance test due to the change of state data during the whole life cycle
